Abstract: Provided is a roller laser texturing processing equipment and its processing method, comprising the following steps: dividing the processing area, determining the distribution scheme: obtaining a distribution scheme of end-to-end, unordered and uniform texturing lattice according to said roller processing unit parameters and morphological parameters; determining the output signal: the laser output position signal, beam energy regulation signal and deflection signal of one-dimensional beam deflection unit are obtained through the information processing module; performing roller laser texturing processing: said laser output position signal is used to control the light source module to emit the laser; said beam energy regulation signal and deflection signal of one-dimensional beam deflection unit are input into the laser terminal output module, respectively, to generate an unordered laser lattice, each laser terminal output module is used to process a roller processing unit.
